python能做的100件事02-代码生成器

简介

代码主要用于生成java web mvc开发需要的entity,dao,service,controller层文件以及公用的mapper文件，基于数据库表结构生成，基于mysql数据库，需要用到的第三方库主要是python连接mysql的库pymysql。通过pip install pymysql命令安装即可。如有不合适的地方请拷贝代码自行修改或定制功能。以下是生成的目录和文件预览，完整代码见文末，如果拷贝代码不方便，可以到此处仓库拷贝代码：

示例数据表代码

CREATE TABLE `pms_user` (
  `id` int(11) NOT NULL AUTO_INCREMENT COMMENT '用户id',
  `name` varchar(64) NOT NULL COMMENT '用户名',
  `full_name` varchar(64) NOT NULL COMMENT '姓名',
  `phone_number` varchar(64) NOT NULL COMMENT '电话',
  `email` varchar(64) NOT NULL COMMENT '邮箱',
  `c_time` timestamp NOT NULL DEFAULT current_timestamp() COMMENT '创建时间',
  `u_time` timestamp NOT NULL DEFAULT current_timestamp() ON UPDATE current_timestamp() COMMENT '更新时间',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_general_ci COMMENT='用户表'
